What appeal statements of case and proofs of evidence cost
There is no fee to appeal, so the budget is drafting, evidence and advocacy. How the document requirements and effort differ between householder, written representations, hearing and inquiry.
The appeal statement of case cost is almost entirely professional time, because the Planning Inspectorate charges no fee to appeal. What you are budgeting for is drafting, evidence assembly, witness preparation and, at inquiry, advocacy. The spread between procedures is wide: a written representations appeal on a small scheme is a few days of work, while an inquiry with three expert witnesses and counsel is an order of magnitude more.
Decide the procedure first, then build the budget from the documents that procedure demands. Working the other way round is how appeals end up under-resourced at exactly the point where the case is won or lost.
Documents required by procedure type
| Procedure | Appellant documents | Practical effort |
|---|---|---|
| Householder appeal service | Appeal form and the original application material only | Half a day to a day |
| Written representations | Full statement of case with the appeal, final comments | Two to five days |
| Hearing | Statement of case, hearing statement, attendance by the agent | Five to ten days plus the hearing |
| Inquiry | Statement of case, proofs of evidence and summaries per witness, statement of common ground, rebuttals, opening and closing submissions | Weeks, across several people |
The householder route is deliberately spare. No further statements are allowed beyond the appeal form and what was already before the council, which means the appeal is won or lost on the material submitted with the application. Writing a better planning statement at application stage is therefore the least expensive appeal insurance there is, and the thinking behind that document is set out on the planning statement page.
Deadlines differ too. The general deadline to appeal is six months from the decision, reduced to 12 weeks for householder and minor commercial appeals, so the budget conversation has to happen quickly.
Statement of case against full proof of evidence
These two documents are often confused, and they cost very different amounts.
A statement of case sets out the full particulars of the case a party intends to make, with the policies relied on and the documents to be produced. It is a scope document. It binds you, because an inspector will not welcome a new argument that appears later, and it is normally drafted by the planning consultant leading the appeal.
A proof of evidence is a witness's own signed evidence on a defined topic, written in the first person, with appendices. One per witness, per topic. Under the inquiry procedure rules, proofs are due no later than four weeks before the inquiry, and where a proof runs beyond 1,500 words a summary has to be provided as well. That summary is what gets read aloud, so it deserves real drafting time rather than a cut-and-paste of the headings.
The cost difference comes from the appendices and the cross-examination risk. A planning proof that cites 30 appeal decisions needs each one read, checked and summarised, and the witness has to be able to answer questions on all of them.
Expert witness time and rehearsal
Budget each witness in four parts: reading in, drafting the proof, preparing the summary, and rehearsal. The last one is routinely left out and routinely needed.
Rehearsal means someone other than the witness reading the proof adversarially and asking the questions the other side will ask. Half a day per witness, done properly, saves more than it costs. For a technical witness on viability, highways or heritage, the exercise also exposes the points where two of your own witnesses say slightly different things, which is the gift an opposing advocate hopes for.
Where viability is in issue, the appeal evidence is often the most expensive single item, partly because inputs have to be updated to the inquiry date. We look at how to budget for that work and its review mechanism in our note on budgeting a viability assessment, and the underlying document is described on the viability assessment page. Councils expect a suitably qualified author for that work, and professional review is strongly advised.
An illustrative day-count budget
Take a 40-dwelling scheme refused on landscape and highway grounds, going to inquiry with three witnesses. An illustrative effort profile might run: statement of case two days, planning proof eight days, landscape proof six days, highways proof five days, statement of common ground three days shared, rebuttals four days, rehearsal two days, inquiry attendance four days each for the witnesses who are called. Convert those days at your own charge-out rates and the consultant team cost appears before counsel is added. The day counts are illustrative only; a complex heritage or Green Belt case can double them.
Counsel at inquiry and its cost
Most appellants at inquiry use counsel for advocacy, and that is a separate instruction from the consultant team. The fee structure is normally a brief fee covering preparation plus a daily rate for the hearing days, with the brief fee reflecting the amount of reading.
Three things reduce it. A tight statement of case, so counsel is not reading around the issues. A properly agreed statement of common ground, so fewer matters are live. And proofs delivered on time, because late proofs mean counsel preparing twice.
Rates vary widely by seniority and region, so ask for a fee estimate in writing against a named timetable rather than relying on an hourly figure.
Rebuttal proofs and late evidence
Rebuttals are optional and sometimes necessary. They answer new material in the other side's proofs rather than restating your own case, and an inspector will say so if yours does the latter.
The budget risk is that rebuttal work lands in the fortnight before the inquiry, when the team is least available. Reserve time for it rather than hoping. Late evidence is worse: material produced during the inquiry can be admitted, but it invites an adjournment application, and an adjournment caused by one party's conduct is one of the routes to an award of costs against them.
Costs awards work both ways and turn on unreasonable behaviour rather than on who wins. A council that fails to substantiate a reason for refusal, or an appellant who withdraws at the door of the inquiry, both risk the same outcome.
Statement of common ground as a saving
The least costly document in the appeal is the one that removes an issue. A statement of common ground records the facts both parties agree: site description, planning history, policy context, trip rates, housing land supply figures, dimensions, the content of the consultation responses.
Every agreed line is a line nobody pays a witness to prove. Push for it early, before proofs are drafted rather than after, and keep it factual. Where the council is short of officer time, offering a first draft usually gets it agreed.
Expect to spend real effort on it anyway. Two or three days of negotiation over wording is normal, and it pays for itself in shorter proofs and a shorter inquiry.
Budgeting by procedure before you appeal
Run the arithmetic before submitting the appeal, not after the inspector determines the procedure. The sequence that works:
- Establish the real reasons for refusal and which of them need expert evidence rather than argument.
- Choose the procedure you will request and say why on the appeal form.
- Price the documents that procedure requires, witness by witness, in days.
- Add rehearsal, rebuttal reserve and counsel's brief fee.
- Compare the total against the cost of a revised application, which for some schemes is the better buy.
That last comparison is the one clients value most. An appeal that costs more than redesigning and resubmitting, with no costs recovery available even on success, is rarely worth running on a point of principle alone. The same logic applies to conditions you cannot discharge, as we set out in the cost of a pre-commencement condition you cannot discharge.

Frequently asked questions
Is there a fee to lodge a planning appeal?
No. The Planning Inspectorate does not charge appellants a fee for a planning appeal, so the cost is the professional time spent preparing the case and, at inquiry, advocacy. That is also why a weak application is expensive later: the appeal itself is free to start but the evidence needed to win it is not.
What is the difference between a statement of case and a proof of evidence?
A statement of case sets out the full particulars of the case a party will make, with the policies and documents relied on, and it binds the scope of the argument. A proof of evidence is a named witness's own signed evidence on one topic, written in the first person with appendices, and is due four weeks before an inquiry.
When does a proof of evidence need a summary?
Under the inquiry procedure rules, a proof running to more than 1,500 words must be accompanied by a summary, and the summary is what the witness presents at the inquiry. Treat it as a document in its own right rather than a condensed table of contents, because it frames how the inspector first hears the evidence.
How does a statement of common ground reduce cost?
It records the facts both parties accept: site description, planning history, policy context, agreed trip rates, dimensions and consultation responses. Every agreed fact is one nobody pays a witness to prove, which shortens proofs and the inquiry itself. Negotiate it before proofs are drafted, and offer the first draft if the council is short of officer time.
Can I recover my appeal costs if I win?
Not as a matter of course. Costs awards turn on unreasonable behaviour by a party rather than on the outcome, so winning does not by itself produce an award. A council that cannot substantiate a reason for refusal, or a party that causes an adjournment, risks an award against it. Keep a record of the conduct you may later rely on.
